Constant disconnect

I just had a game, first game of the day. I shouldn't have done ranked and instead done normal. But usually my games run fine so I didn't expect this issue to happen. But I disconnected constantly. Whenever I walked to lane I disconnected, whenever a fight started, I disconnected. I could only farm for 2 seconds or I disconnected. I tried to restart, replug my cable... but nothing changed. I'd probably get a lot of reports from that, I got the leaver note as well which sucked. I don't know what's going on, my internet is fine, my ping was stable at 20 the whole time... It just sucked that I had to ruin a game like that, not just for myself but for my teammates as well. Is there a way to get this to tech support with the right information to see what has happened?
